Duet Buddy - a proof of concept remote monitor

richardmckenna

@o_lampe for me my printers are upstairs in my office. If I’m downstairs I put the M5Stack somewhere in my line of sight so a quick glance would give me an update on the status of the print. With a phone, I would either have to leave it on with the app running propped up somewhere or have to pick it up, unlock it and switch to the app if it’s not the active app. In this scenario it makes more sense to me to have a small dedicated display.

@richardmckenna Have you shared the new code on github? I have everything setup, I just need to know the address to request from for the Duet 3's.

richardmckenna

@pastthepoint yes just done it, apologies for the delay you can find the pull request here https://github.com/zapta/duet_buddy/pull/1 and the .ino file from the pull request here https://github.com/zapta/duet_buddy/blob/261d93e3068ab4e7ba31b516a9a3a7061c9fcd3a/arduino/arduino.ino

@zapta any issues give me a shout

Thanks Richard. The pull request should be in now. Let me know if there is any problem.

Since you are now the active developer, would you like me to point my repository to yours (via a link in the main page), making yours the main one?

richardmckenna

@zapta you can do, happy to continue making little tweaks to it. Next on the list is multiple printers.

zapta

@richardmckenna, what github repository to point to?

Also, if it's a fork of mine, you may want to decouple it since it will be now the system of record.

richardmckenna

@zapta https://github.com/richard-mckenna/duet_buddy

Will do thanks!

zapta

@richardmckenna, done https://github.com/zapta/duet_buddy

Please let me know when you will decouple from my repository.

Edit: Also updated the link at the top post here.

zapta

Transition done. Deleted the source code and added your pictures to entice visitors to click on the link.

Hello,
I adopted the Code a litte for using it with M5Stack Core2 AWS.
It needs only a few changes in the Code, mostly in the Battery level check.

I have changed the HTTP Communication because, when you set a password on the Duet it wont connect properly

  String protocol = "http://";
  String con = "/rr_connect?password=";
  String login_url = protocol + doc["printer_ip"].as<String>() + con + doc["printer_pass"].as<String>();

  Serial.println(login_url);

  String query = "/rr_status?type=3";
  String status_url = protocol + doc["printer_ip"].as<String>() + query;
  
  Serial.println(status_url);

  String dis = "/rr_disconnect";
  String logout_url = protocol + doc["printer_ip"].as<String>() + dis;

  Serial.println(logout_url);

  //Start Connecting to Duet when Wifi is connected
  if (wifi_connected and com == 0) {
    com = 1;
    Serial.println("Wifi Connected");
  }

  // Connect to duet and send a Get status http request.
  http.useHTTP10(true);
  switch (com) { 
    case 1: {
      http.begin(config.printer_pass);
      Serial.print("[HTTP] GET ");
      Serial.println(config.printer_pass);
      com = 2;
    }
    break; 
    
    case 2: {
      http.begin(config.printer_ip);
      Serial.print("[HTTP] GET ");
      Serial.println(config.printer_ip);
    }
    break;
 
    case 3: {
      http.begin(config.printer_diss);
      Serial.print("[HTTP] GET ");
      Serial.println(config.printer_diss);
      M5.shutdown();
    }
    break;
    default : {
      com = 0;    
    }
    break;
  }
  const int httpCode = http.GET();
  Serial.printf("[HTTP] GET... code: %d\n", httpCode);

Also edit the SD Card Variables

 {
"wifi_ssid" : "xxx",
"wifi_password" : "yyy",
"printer_name" : "zzz",
"printer_ip" : "xxx.xxx.xxx.xxx",
"printer_pass" : "yyy",
"printer_diss" : ""
 }

The only thing where i struggle a bit, is to Logoff corectly when Battery level is low or Poweroff is pressed.

Have you interest in the full code for M5stack Core2/CoreAWS, for your Github?

I know this is an old thread but I'm wondering if any has gotten this to work with Duet 3+RPI? My RPI4 is connected to my 5G wifi but it seems because the M5 cannot connect to 5G it cannot connect to the Duet.

jay_s_uk

@dhusolo I don't think it works with duets and SBCs so it's standalone only

dhusolo

@jay_s_uk Yup can confirm. It works on my Duet 2 WiFi with RRF 3.2.2 but can't connect to Duet 3 with SBC regardless what WiFi frequency the SBC is connected to

zapta

Just stumbled upon this one. It includes an MCU, battery, display, Wifi and a wrist band. With the right firmware it can be the first wearable Duet monitor/controller.

@zapta And what a fashion statement!
